Special Issue Information

Dear Colleagues,

This Special Issue is focused on original research articles and critical reviews on the “Latest Updates in Soft Magnetic Materials". The main aim is to focus on related topics by publishing the current developments in soft magnetic materials. 

Soft magnetic materials have high magnetic permeability (μ) and low coercivity (Hc), and they are mainly used in the manufacturing of inductors, transformers, sensors, and other applications that require rapid magnetization and demagnetization. With the development of industrial technology, the demand for high-performance soft magnetic materials is increasing, especially in high-frequency working environments. Soft magnetic materials have become an indispensable subcategory in the field of engineering magnetic materials due to their significant value in cutting-edge technological fields such as electric motors, transformers, and sensors. According to whether the atomic arrangement within the material structure is orderly, soft magnetic materials are divided into crystalline and amorphous soft magnetic materials. Metal soft magnetic alloys (mainly composed of Fe) and soft magnetic ferrite (Fe3O4 and other oxides) belong to crystalline soft magnetic alloys. Amorphous soft magnetic alloys mainly include Fe-based amorphous alloys, Co-based amorphous alloys, and nanocrystalline soft magnetic alloys derived from amorphous materials. Easy magnetization and demagnetization are the characteristics of soft magnetic materials, and the performance requirements for the required devices vary in specific applications. Usually, soft magnetic materials are required to have characteristics such as high Curie temperature, high magnetic permeability, high electrical resistivity, and low coercivity. 

This Special Issue of Magnetochemistry on the “Latest Updates in Soft Magnetic Materials" will closely follow research in this topic to highlight the recent achievements in soft magnetic materials from leading groups around the world. The synthesis, structure, and properties of soft magnetic materials and their applications are appreciated.

In particular, the topics of interest include, but are not limited to, the following:
•  soft magnetic ferrite;

  •  iron silicon alloy;
  •  iron aluminum alloy;
  •  iron silicon aluminum alloy;
  •  nickel iron alloy;
  •  iron cobalt alloy;
  •  amorphous soft magnetic alloy;
  •  ultrafine crystalline soft magnetic alloy;
  •  soft magnetic composites;
  •  new soft magnetic materials.

Metal magnetic memory testing technology can not only detect macroscopic defects in ferromagnetic materials but also rapidly and conveniently detect early damage and stress concentration areas of components. Therefore, it is widely used in the nondestructive testing of ferromagnetic materials. However, the mechanism of magnetic memory detection is not yet clarified, and experimental research is unsystematic. Previous studies mainly focus on the normal and tangential components of magnetic memory signals (MMSs), and the third directional component is rarely considered, resulting in problems such as missed detection and misjudgement in practical applications. In this research, specimens without and with a circular hole defect were designed, and the correlation between the 3D MMS and the defect size, as well as the applied load, were investigated using tensile tests. Magnetic parameters were defined to characterize the stress and defect-induced abnormal magnetic change. The effects of applied load and defect size on magnetic parameters were discussed. The experimental results showed that the peak–valley difference in the 3D MMS increases with increasing load and defect size, and the peak–valley spacing in the 3D MMS is not influenced by applied load but increases with increasing defect size. The 3D MMS gradient exhibits a good correlation with the equivalent stress along the loading direction. Additionally, the applied load and defect size were quantitatively evaluated by utilizing the Lissajous figure area generated from the X and Z components of the 3D MMS. Finally, a nonlinear fitting equation for defect size evaluation was presented. This study can provide a theoretical basis for the quantitative detection and evaluation of defect size and stress in engineering applications. Full article
